Abstract

The invention provides a hearing aid external howling suppression method and equipment. The method comprises the following steps: framing a received first audio to obtain a first framed audio, judging the first framed audio frame by frame to determine the content of the received first audio and similarly obtain the content of a second audio, and if the content of the first audio is the same as the content of the second audio, determining the content of the second audio; and if yes, determining that the second audio is the external howling of the hearing aid, and synthesizing the first amplified audio and the second amplified audio to complete suppression of the external howling of the hearing aid. The external howling of the hearing aid can be effectively inhibited, and the user experience of a hearing-impaired patient using the hearing aid to obtain external sound is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of hearing aid filtering, and in particular to a method and device for suppressing external howling of a hearing aid. Background technique [0002] Wearing hearing aids is the best solution for hearing-impaired patients to restore their hearing. In the process of using a hearing aid, due to the high integration and small size of the digital hearing aid, the signal output from the speaker can easily leak out from the gap between the earplug and the ear canal or the vent hole of the hearing aid. The leaked sound signal is picked up again by the microphone and output again from the speaker, which forms a closed feedback loop. When the gain of the entire system is too large and meets certain phase conditions, it will cause system instability, and eventually cause the hearing aid to produce external howling, which will affect the experience of hearing-impaired patients with hearing aids...
